Présentation du produit & avantages clés
Phenylphosphinic acid has a reactive P–H bond and an acidic P–OH group on a phenyl ring, which makes it both a mild reducing agent and a useful phosphorus building block. In polyamide production it is added during polymerization as a catalyst and stabilizer that helps nylon keep its color and heat stability. It is also an intermediate for phosphorus-based flame retardants and for dye, pesticide and pharmaceutical synthesis.
Essai, moisture and related phosphorus acids are the parameters most buyers compare.
Phosphorus building block
A P–H intermediate for phosphinate flame retardants and other organophosphorus chemistry.
